We have a number of options for iPod!
The mounts on this page (eCaddy Diamond) are the cleanest-looking iPod mounts (in our opinion). However, you cannot have a case or cover on the iPod to use these mounts (it must be a 'naked' iPod!). AND, they are not available for the iPod Touch 5.
Here are some other mounts that also work with the iPod (including the iPod Touch 5):
If you just can't part with your case or cover, you will want to check out the X-Grip Adaptor Mount.
If you have a cover with a belt clip, you can use the eCaddy Belt Clip Mount.
If you need waterproofing, see the eCaddy Ultra Mounts and the eCaddy Deluxe Universal Mount.
